How to put on (and take off) an Otterbox Defender Case for iPad

This case is amazing. I don't see how it is too much trouble because you never take it off. I take mine on a construction site every week and am glad to have the extra protection. I use a sleeve to protect the screen while traveling too.

I missed the Otterbox because I was blown away by this redhead's sleeves with thumbholes and finger full of rings. Why would anyone wear something like that when doing manual tasks with delicate electronics?
